remove OSS gateway due to lack of licensing (#9390)

OSS go sdk lacks licensing terms in their
repository, and there has been no activity

On the issue here https://github.com/aliyun/aliyun-oss-go-sdk/issues/245

This PR is to ensure we remove any dependency code which
lacks explicit license file in their repo.

-# MinIO OSS Gateway [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)
-MinIO Gateway adds Amazon S3 compatibility to Alibaba Cloud Object Storage Service (OSS).
-
-## Run MinIO Gateway for OSS.
-
-### Using Docker
-```
-docker run -p 9000:9000 --name azure-s3 \
- -e "MINIO_ACCESS_KEY=ossaccesskey" \
- -e "MINIO_SECRET_KEY=osssecretkey" \
- minio/minio gateway oss
-```
-
-### Using Binary
-```
-export MINIO_ACCESS_KEY=ossaccesskey
-export MINIO_SECRET_KEY=osssecretkey
-minio gateway oss
-```
-
-## Test using MinIO Browser
-MinIO Gateway comes with an embedded web based object browser. Point your web browser to http://127.0.0.1:9000 to ensure that your server has started successfully.
-
-![Screenshot](https://raw.githubusercontent.com/minio/minio/master/docs/screenshots/minio-browser-gateway.png)
-
-## Test using MinIO Client `mc`
-`mc` provides a modern alternative to UNIX commands such as ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services.
-
-### Configure `mc`
-```
-mc config host add myoss http://gateway-ip:9000 ossaccesskey osssecretkey
-```
-
-### List buckets on OSS
-```
-mc ls myb2
-[2017-02-22 01:50:43 PST]     0B ferenginar/
-[2017-02-26 21:43:51 PST]     0B my-bucket/
-[2017-02-26 22:10:11 PST]     0B test-bucket1/
-```
-
-### Known limitations
-
-Gateway inherits the following OSS limitations:
-
-- Bucket names with "." in the bucket name are not supported.
-- Custom metadata with "_" in the key is not supported.
-
-Other limitations:
-
-- Bucket notification APIs are not supported.
-
-## Explore Further
